HEB (heb.com) Blocks account access using Firefox Firefox will load the site page but you can no longer access your account. it gives you the error message: error: invalid_request error_description: interaction session and authentication session mismatch. They tell you you have to use Chrome, they no longer support Firefox. I do not know where to ask for Firefox for help with this issue. HEB has blocked account access using Firefox and say they only allow Google Chrome
